Process Inputs

[DANZIG]

Hello I have an external commandline proccess that I need to execute. The process takes 2 inputs though the first is an ARGV the second is the RUNNING process asking for another piece of information. As I'm calling the process using backticks`` I can't feed it the second piece on information that follows the processing of the first. I am running this on a NT box. If I'm going about it the wrong way please let me know (An exapmle would be nice) or if there's just a step I'm missing.

Thanks in advance.

why not just run the script with two inputs from the command line like:

$valueA = @ARGV[0];
$valueB = @ARGV[1];

or do your inputs have spaces in them?

Well the problem is that it's being fed 2 ARGVS and can't be passed the 3'rd on the command.

Prog ARGV1 ARGV2
H:\>runas /user:someuser scandisk.exe


After execution you are prompted for this.


Enter password for someuser:

Any ideas on how to wait for the proccess to request an input and send the 3'rd ARGV (somepassword) ?

You could try running the command on the end of a pipe, like this:
[tt]
open(CMD, "|runas /user:someuser scandisk.exe&quot
[tab]|| die "$!"
print CMD "thepassword\n";
close(CMD);
[/tt]

It's a way of running a command and then feeding stuff (the password, in this case) into it's STDIN.

This may or may not work, depending upon whether or not the runas program uses STDIN to accept its input.

I don't know if you could mask the input of the keyboard, but you can use STDIN to get input from the console while the script is running. For example:

#!/usr/bin/perl
print "Enter your password:";
$password = <STDIN>;
print &quot;Your password was:$password&quot;;

.......

This script will look something like this when run:

Enter your password:mypassword
Your password was:mypassword
